Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating 3D digital models of aircraft elements for augmented reality inspection face challenges due to the lack of available CAD models, confidentiality issues, and insufficient or unusable CAD models, limiting the accuracy and completeness of augmented reality images.
Innovation Solution
A method involving scanning aircraft elements to create digitized points, forming a 3D mesh, and modifying it to add missing patterns, using computer-aided design software to produce accurate 3D models without relying on CAD software, and employing mesh correction and simplification techniques to enhance accuracy and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CAD software is used to create 3D models, then model accuracy is improved, but model availability deteriorates (models are confidential or insufficient)
Solution Approach 1:
The patent creates 3D models by scanning physical aircraft elements and generating digital replicas through point cloud processing and mesh generation, rather than relying on original CAD models. This copying approach allows creation of models for elements where CAD models are confidential or unavailable, while maintaining geometric accuracy through multiple scanning angles and iterative refinement
Solution Approach 2:
The patent performs preliminary scanning and mesh generation to create initial 3D models before augmented reality inspection. This preliminary action includes capturing point clouds from multiple angles, generating initial meshes, and identifying missing patterns in advance, allowing the inspection system to work with complete models rather than discovering gaps during inspection
2Loss of information
If complete scanning of all aircraft elements is performed, then model completeness is improved, but scanning time increases
Solution Approach 1:
The patent performs scanning from multiple angles and generates initial meshes that may contain gaps or incomplete regions. Rather than attempting to scan every possible angle perfectly, the system takes partial actions (scanning from key angles) and then uses computational methods to identify and fill missing patterns through mesh correction and iterative refinement processes
Solution Approach 2:
The system performs preliminary scanning to capture all visible surfaces, then separately identifies and fills missing patterns through computational geometry operations. This separates the time-consuming scanning phase from the model completion phase, allowing efficient scanning without compromising final model completeness
3Measurement precision
If high-resolution scanning is performed, then model accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent processes scanned data by dividing it into manageable components: raw point clouds are segmented into multiple views, meshes are divided into regions for targeted correction, and missing patterns are identified and filled separately. This segmentation allows high-resolution scanning while managing data complexity through systematic processing stages
Solution Approach 2:
The system performs comprehensive scanning to capture all details, then selectively processes only the portions that contain errors or missing patterns. Rather than uniformly processing entire high-resolution models, the system applies corrections only where needed, reducing overall processing complexity while maintaining accuracy

AI summary
Method for creating a 3D digital model of at least one aircraft element in order to produce augmented reality image(s), the method including the steps of: a) scanning, at least one element of an aircraft so as to produce a set of digitised points representative of the 3-dimensional shape of the element, then, using a computer and/or at least one computer processing unit; b) forming, from the set of digitised points, at least one 3D mesh representative of the shape of the element; c) modifying a replica of the given mesh so as to add a missing geometric pattern corresponding, in particular, to a pattern of the element located in its inner volume and/or which is located outside the field of view of the scanner during the scanning in step a).
